Abstract
A method for discontinuous reception operation for carrier aggregation comprising: receiving a first set of discontinuous reception parameters for a first carrier and a limited or different set of discontinuous reception parameters for a second carrier; and configuring discontinuous reception parameters on the first carrier and second carrier.
Description
Technical field
The disclosure relates to senior Long Term Evolution (LTE-A), more specifically, relates to discontinuous reception when to use carrier aggregation in LTE-A.
Background technology
Discontinuous reception allows subscriber equipment (UE) during each time period, to close wireless set to save the battery life of UE.In Long Term Evolution (LTE) specification, even if in the connection mode, UE is also allowed to enter discontinuous reception (DRX).Operate at the 3.1st and 5.7 joint DRX defined for single carrier operation of LTE version 8,3GPP TS 36.321, its full content is incorporated in this by reference.
In senior LTE (LTE-A), reach an agreement: can carrier aggregation be used, so that for the wider transmission bandwidth of possible peak-data rates support improved, to meet LTE-A demand.Under carrier aggregation, be polymerized multiple component carrier and in subframe, multiple component carrier can be distributed to UE.Therefore, each component carrier can have the bandwidth of such as 20MHz, and the system bandwidth of total polymerization reaches 100MHz.UE can carry out receiving or sending based on its ability on multiple component carrier.In addition, carrier aggregation can be carried out when carrier wave is positioned at same band and/or carrier wave is positioned at different bandwidth.Such as, a carrier wave can be positioned at 2GHz place, and second polymerization carrier wave can be positioned at 800MHz place.
DRX operation is transformed into multicarrier lte-a system existing problems from single carrier LTE Rel-8 system.DRX under LTE Rel-8 possibly cannot to operate or invalid when using multiple carrier wave.LTE-A forum proposes two schemes.
In R2-092959 " DRX with Carrier Aggregation in LTE-Advanced ", describe a kind of suggestion, wherein, configure different DRX parameters independently for different component carriers, and perform DRX independently for each component carrier.Such as, one-component carrier wave can use short DRX cycle, and another component carrier only can use long DRX cycle; Or the DRX cycle configured for different component carriers is completely independent from one another.The problem of the program is that UE keeps the complexity needed for different states or timer for different carrier waves.Between carrier wave, have the income that completely independently DRX cycle and timer bring may be very little.Because upper-layer service is over a number of carriers multiplexing, therefore, make decision to determine on which carrier wave, send coding groups by the scheduler of enode b (eNB).
In the alternative plan that R2-092992 " Consideration on DRX " summarizes, on anchor carrier wave, only configure DRX operation.Based on needing and distributing additional component carrier as required during " effective time " of anchor carrier wave.
But above-mentioned two schemes does not provide the details of the allocation and deallocation about additional components carrier wave.They do not provide the details operated of the DRX about each carrier wave clearly yet.

Embodiment
According to a scheme, provide a kind of discontinuous method receiving operation for carrier aggregation, comprising: receive the first discontinuous parameter receiving set for first carrier and the limited or different discontinuous parameter receiving set for the second carrier wave; And configure discontinuous parameter receiving for first carrier and the second carrier wave.
According to another program, provide a kind of method being enabled or disabled carrier wave reception by media access control unit signaling, comprising: add carrier wave reception and enable or disable command control unit; And the reception of configuration carrier wave enables or disables confirmation control unit.
DRX operation can be used for different objects.Such as, under the UE of the low-grade communication activity of current experience can be in DRX state, wherein, UE wakes up to receive business once in a while from DRX.The example so done can be that UE carries out audio call.Packets of voice has and predictablely occurs pattern, and does not need to send in each subframe, therefore UE can be configured to continuous speech packet transmission/reception between time be used in DRX under.Another example can be the UE current free time substantially and not have business.UE needs temporarily to wake up to check whether eNB has any business for UE.
DRX can also be used for the object of resource-sharing.Particular UE has data transmission constantly in each subframe and/or receives is unlikely.Therefore, in order to signalling efficiency, if additional delay can be tolerated, then more wish data to merge into less and larger Resourse Distribute.This delay is usually very little.
Such as, every 10 subframes and the pulse (instead of in each subframe of these 10 subframes send 10 100 bytes) that sends 1000 bytes in a subframe is more effective.Due to the sharing characteristic of Packet Data Channel, other UE can current UE be not in receive or send subframe during usage data channel.Therefore, UE can be configured to enter DRX when eNB knows and can't send to UE.ENB will send to other UE in these subframes.
One skilled in the art will recognize that to there is different DRX cycle length, such as, for 10 milliseconds of long DRX cycle and for 2,5,8 and 10 milliseconds of short DRX cycle, therefore can share object for this data channel and use DRX function.In addition, but multiple UE can be configured with identical DRX cycle length have different start offsets.This can cause the UE of different group to wake up during the different time intervals, thus is convenient to carry out the time-division between multiple UE.
With reference now to Fig. 1, Fig. 1, show LTE Rel-8 to operate.In FIG, highly show effective model 110 first, highly show DRX mode 112 second.During effective model 110, UE monitors downlink control channel for Resourse Distribute possible on down link or uplink communication channel.In the time shown in reference symbol 120, run into the border of DRX cycle.At this some place, pattern becomes effective model 110 from DRX mode 112.In addition, OnDuration (continuing) timer 122 is started.OnDuration timer 122 represents the duration that UE will remain under effective model, though this duration not from/go to the business transmission of UE.
In the example of fig. 1, under effective model, arrow 130 illustrates: receive last physical downlink control channel (PDCCH), and it indicates the up link for new grouping transmission on the new grouping transmission on physical down link sharing channel (PDSCH) or physical uplink link shared channels (PUSCH) to authorize.At this some place, start DRX inactivity timer 132.DRX inactivity timer 132 defines in the number of pointer to the continuous P DCCH subframe recently successfully after decoding of the PDCCH that the initial uplink of UE or downlink user data send.One skilled in the art will recognize that in the example of fig. 1, UE remains on effective model 110 times, until DRX inactivity timer 132 expires.Arrow 134 shows expiring of DRX inactivity timer 132, and at this some place, UE changes DRX mode 112 into.
Total duration between time shown in reference symbol 120 and arrow 134 is called as effective time 136.As regulation in the sub-clause 5.7 of the LTE Rel-8DRX specification of 3GPP TS 36.321, effective time 136 operates relevant with DRX, and define effective time 136 UE supervision PDCCH the subframe that continues.
The packet of the last transmission shown in arrow 130 can retransmit by expectability hybrid automatic repeat-request (HARQ).Arrow 140 shows the first point that it is expected to HARQ and retransmit.At this some place, if UE needs HARQ to retransmit, then start DRX retransmission timer 142, during this time period, HARQ can be received and retransmit.If do not receive HARQ to retransmit, then DRX retransmission timer expires at 143 places.No matter DRX inactivity timer is running or DRX retransmission timer runs, and UE remained in effective time.
According to content above, can recognize, therefore effective time 136 may be extended by data activity, and this can cause DRX inactivity timer to be reset.In addition, if having HARQ to retransmit for the PDSCH grouping expection previously sent, then start corresponding DRX retransmission timer, effective time 136 is extended.
If UE is configured to for short DRX cycle, then as shown in the arrow 150 of Fig. 1, start new effective model 110 in short DRX cycle end.Arrow 150 shows DRX cycle, which specify OnDuration periodicity repeat, after followed by possible section ineffective time.
Also may have long DRX cycle 152 as shown in Figure 1.Usually, long DRX cycle 152 is longer than short DRX cycle, and both can be configured by eNB.
UE can be configured with DRX function by wireless heterogeneous networks (RRC), and DRX function control UE is for the cell-radio network temporary identifier (C-RNTI) of the PDCCH surveillance operation of the following: UE, transmission power control physical uplink control channel RNTI (TPC-PUCCH-RNTI), transmission power control physical uplink link shared channels RNTI (TPC-PUSCH-RNTI) and semi-persistent scheduling C-RNTI (SPS C-RNTI) (if being configured with).When under RRC_CONNECTED, if be configured with DRX, then UE is allowed to use the DRX operation of sub-clause 5.7 defined of LTE Rel-8 specification 3GPP TS 36.321 to monitor PDCCH discontinuously.Otherwise UE monitors PDCCH continuously.When using DRX operation, UE also monitors PDCCH according to the requirement found in other sub-clauses of this specification.RRC operates by being configured to lower content control DRX: the value (being the subframe of DRX cycle startup place) of OnDuration (continuing) timer, drx-InactivityTimer (drx-inactivity timer), drx-RetransmissionTimer (drx-retransmission timer) (each DL HARQ procedure has, except broadcasting process), DRX Start Offset and optional DRX Short Cycle Timer (DRX short cycle timer) and Short drx-Cycle (short drx cycle).Also for each downlink HARQ procedure definition HARQ retransmission timer (RTT) parameter, this parameter defines the minimum subframe amount before UE expects downlink HARQ re-transmission.
5.7 joints of LTE Rel-8 specification 3GPP TS 36.321 define following content:
When configuring DRX cycle, Active Time (effective time) comprises the following time:
-onDurationTimer or drx-InactivityTimer or drx-RetransmissionTimer or mac-ContentionResolutionTimer (as described in sub-clause 5.1.5) just operationally; Or
When-the dispatch request that sends on PUCCH is also unsettled (as described in sub-clause 5.4.4); Or
-for unsettled HARQ retransmit up link authorize may occur and in the harq buffer device of correspondence, have data time; Or
-when not yet receiving the PDCCH of the new transmission of the instruction of the C-RNTI being addressed to UE after successfully receiving the accidental access response for the lead code of explicit signaling (as described in sub-clause 5.1.4).
When configuring DRX, UE should for each subframe:
If-employ short DRX cycle and [(SFN*10)+subframe numbers] modulo (shortdrx-Cycle)=(drxStartOffset) modulo (shortdrx-Cycle); Or
If-employ long DRX cycle and [(SFN*10)+subframe numbers] modulo (Longdrx-Cycle)=drxStartOffset:
-start OnDurationTImer.
Expire in the burst and the data of successfully not decoding in the soft buffer of corresponding HARQ instance process if-HARQ RTT is Timer (HARQ RTT timer):
-start drx-RetransmissionTimer for corresponding HARQ instance process.
If-receive DRX order MAC Control Element:
-stop OnDurationTimer,
-stop drx-InactivityTimer.
If-in the frame drx-InactivityTimer expire or receive DRX order MAC Control Element:
If-be configured with short DRX cycle:
-start or restart DRXShortCycleTimer;
-use short DRX cycle.
-otherwise:
-use long DRX cycle.
If-DRXShortCycleTimer expires in the burst:
-use long DRX cycle.
-during effective time, for PDCCH subframe (except the up link that operates for half-duplex FDDUE send required for subframe and subframe except the part as configured measurement clearance):
-monitor PDCCH;
If-PDCCH indicates DL to send or the DL distribution for this sub-frame configuration:
-start HARQ RTT timer for corresponding HARQ instance process;
-stop drx-RetransmissionTimer for corresponding HARQ instance process.
If-PDCCH indicates new transmission (DL or UL):
-start or restart drx-InactivityTimer.
-when not in effective time, should not report the CQI/PMI/RI about PUCCH and SRS.
No matter whether UE monitors PDCCH, and when expecting, UE receives and sends HARQ feedback.
After attention: UE can select to receive the PDCCH of the new transmission (UL or DL) of instruction alternatively in the last subframe of effective time, on PUCCH, do not send CQI/PMI/RI report and/or SRS sends reaching in 4 subframes.Select on PUCCH, do not send CQI/PMI/RI report and/or SRS sends and is not suitable for the subframe that OnDurationTimer running.
DRX in LTE-A
According to the disclosure, provide for utilizing the DRX in LTE-A to support the various embodiments of carrier aggregation.
In one embodiment, UE should have it and enables Signal reception and the component carrier simultaneously meeting the minimal amount needed for business demand.There is complexity and power consumption that completely independently DRX cycle makes no longer to need UE place between the multiple component carriers distributing to UE.In one embodiment, can between the component carrier distributing to UE the coordinated DRX cycle of tool.
Each species diversity between LTE and LTE-A may affect DRX operation, therefore may need to be solved by LTE-ADRX solution.
First difference is that LTE has a down link and a uplink carrier.There is man-to-man mapping between the two carriers.On the contrary, in LTE-A, not only may there is multiple down link and/or multiple uplink carrier, and the number of down link may be different with the number of uplink carrier.Therefore, direct man-to-man association may be there is no between down link and uplink carrier.
Can recognize, in LTE and LTE-A, all when UE is in DRX operation must always desirably receives and send HARQ feedback.In the LTE-A with carrier aggregation, this means, the respective components carrier wave in down link and up link must be remained valid to receive or to send this information.
In LTE, the resource instruction on PDCCH corresponds to the uplink carrier of identical downlink carrier or association, this is because only there is a carrier wave on each link direction.In LTE-A, the PDCCH signaling on a carrier wave (such as anchor carrier wave) can be associated with the transmission on other up links multiple or downlink carrier or reception.As those skilled in the art be familiar with, " anchor carrier wave " also can be called " main carrier ", and " non-anchor carrier wave " also can be called " subcarrier ".
Another difference is between the two, because the PDCCH on a carrier wave is associated with the reception on other up links multiple or downlink carrier, expection only at a carrier wave (such as, non-anchor carrier wave) on the UE that retransmits of HARQ also need to keep receiving different carrier wave (such as, anchor carrier wave), retransmit relevant PDCCH information to receive with possible HARQ.
In addition, the LTE-A with the carrier wave of multiple polymerization has a large amount of HARQ procedure.If HARQ procedure can retransmit by expectability HARQ arbitrarily, then UE can be in effective time.Due to a large amount of HARQ procedure, thus UE be in effective time possibility for LTE-A far above LTE, the percentage of time being therefore in effective time is also far above LTE for LTE-A.

When UE is in RRC_CONNECTED state, can distribute N number of component carrier, wherein N is more than or equal to 1.One or more in N number of component carrier can be assigned as designated carrier.In one embodiment, designated carrier also can be " anchor carrier wave ".UE can carry out carrier wave reception on all N number of component carriers.Term " carrier wave reception " is defined as: when the carrier wave that UE can carry out component carrier receives, and UE enables RF on this component carrier and receives and/or the reception of the Downlink Physical control channel relevant to this component carrier and Downlink Physical Control channel.Carrier wave receives can also be called Signal reception or some other term, and can not deviate from the disclosure.As those skilled in the art be familiar with, if the carrier wave forbidding component carrier for UE receives, then UE stops the decoding to PDSCH, PDCCH and other control channels relevant to this component carrier, and no matter PDCCH is at the carrier wave identical from PDSCH Resourse Distribute or sends on different carrier waves.PDCCH in the subset that UE only can monitor one or more upper, the N number of component carrier in designated carrier or on all N number of component carriers.If UE detects the PDCCH distributing PDSCH resource on certain components carrier wave, then UE performs base band demodulating and the decoding of the PDSCH resource of distributing on this component carrier.
ENB by adding new component carrier to set or remove existing component carrier from set, can change the set of N number of component carrier.ENB can also change one or more designated carrier.
Can configure DRX function by RRC signaling to UE, the carrier wave of DRX function control UE on one or more component carrier receives.As used herein, DRX parameter has the definition similar with the definition in LTE Rel-8, and comprise onDurationTimer, drx-InactivityTimer, drx-RetransmissionTimer (each downlink HARQ process one, except broadcasting process), the value of long DRX cycle, drxStartOffset and optional drxShortCycleTimer and short DRX cycle.Also define HARQ retransmission timer for each downlink HARQ process (except broadcasting process).Foregoing does not also mean that restrictive, and other DRX parameters also can be used for each component carrier comprising designated carrier.
Non-designated carrier wave can have various DRX timer and parameter.In one embodiment, non-designated carrier wave can have following timer: such as drx-InactivityTimer, drx-RetransmissionTimer and HARQ RTT Timer (there is latter two timer for each downlink HARQ process).But can omit drx-InactivityTimer in various embodiments, therefore, the parameter used only comprises drx-RetransmissionTimer and HARQ RTT Timer time expiration and arranges.In other embodiments, for non-designated carrier wave, the DRX parameter sets of simplification can be there is.Different non-designated carrier waves can have the DRX parameter sets of different simplification.In another embodiment, some non-designated carrier waves can be configured with whole DRX parameter sets, and other non-designated carrier waves are configured with the DRX parameter sets of simplification.In other embodiments, all non-designated carrier waves can have identical DRX parameter sets (whole or simplification).In another embodiment, eNB only needs to notify a parameter sets for all non-designated carrier signaling number.
ENB passes through RRC signaling to UE signaling DRX parameter.ENB can configure DRX parameter for designated carrier and M other non-designated component carriers, and wherein M is more than or equal to 0.These designated carriers and M non-designated component carrier be eNB may order UE enable carrier wave receive for carrier wave.In one embodiment, eNB UE may be ordered to enable not in the set of designated carrier and M non-designated carrier wave component carrier on carrier wave receive.In another embodiment, all M non-designated component carrier has identical DRX configuration, therefore only needs a common signaling instead of the individual independent setting of M.In other embodiments, for configuration DRX parameter for designated carrier or non-designated carrier wave, eNB can enable or disable DRX parameter by explicitly signaling UE.When enabling DRX operation for carrier wave, UE performs DRX operation according to the regulation of DRX parameter.When forbidding DRX operation, if the carrier wave previously enabled on this carrier wave receives, under UE remains on effective model on this carrier wave.
According to content above, the set of N number of carrier wave can be called effective carrier wave, and configure DRX parameter for designated carrier and the set of M non-designated carrier wave can be called that DRX configures carrier wave.DRX configured carrier wave and effective carrier wave set can overlap also can not be overlapping.The set of effective carrier wave can be also the subset that DRX has configured the set of carrier wave, and vice versa.
Except effective carrier wave and DRX have configured except carrier wave, UE can allocate additional component carrier in advance, and wherein, assignment logic carrier index is to be mapped to specific physical carrier.The set being assigned the carrier wave of logical carrier index can be called candidate carrier.By from the clean culture of eNB or multicast signaling, to the attribute of UE signaling candidate carrier, can also comprise: carrier frequency, bandwidth, control channel support etc.Can for the one or more carrier wave configuration DRX operation in candidate carrier set.The UE of the carrier wave in candidate carrier set is received and by the explicit signaling (such as, RRC signaling or MAC CE) from eNB, can enable, or implicitly enabled by DRX parameter configuration.Such as, this figure 19 illustrates, and wherein, eNB 1910 sends message 1930 to UE 1920.Message 1930 provides the information for carrier wave configuration, comprises carrier wave logic index.Then as shown in arrow 1940, can at UE 1920 place configuration carrier wave.
In one embodiment, the non-designated carrier wave (wherein, M defines as mentioned above) in the set of M carrier wave is associated with designated carrier.One or more non-designated carrier wave can be associated with in designated carrier.By eNB (such as, by RRC signaling) to this association of UE signaling.In one embodiment, eNB in same RRC signaling message to UE signaling DRX parameter and this related information.In another embodiment, by the predetermined mapping of the logical/physical carrier index of non-designated carrier wave and designated carrier, this association can be implicit expression.In another embodiment, eNB can use broadcast or multicast signaling (such as, broadcast or multicast RRC signaling) to the non-designated carrier wave of multiple UE signalings in community and the association between designated carrier.
In one embodiment, for in M non-designated carrier wave (wherein, M defines as mentioned above) each, the carrier wave can enabled on this carrier wave in OnDuration startup place of the designated carrier of association receives, or can receive by the carrier wave enabled during the effective time of the designated carrier of association on this carrier wave.This enabling can be realized by the eNB explicit signaling to UE (such as, PDCCH enables signaling), or by certain alternate ways.
For each in M non-designated carrier wave, by RRC signaling or the MAC CE of such as eNB to UE, can configure and signaling two kinds of patterns.Under rear a kind of pattern, during the effective time on the designated carrier of association, eNB can carry out order UE by control signal and enable carrier wave on another component carrier and receive.This control signal can including, but not limited to RRC signaling, PDCCH signaling or MAC CE signaling.Can send this signaling on the designated carrier of association or on one of N number of component carrier, wherein N defines as mentioned above.
An example of above-mentioned situation is: if UE successfully receive in one of N number of component carrier have C-RNTI instead of SPS C-RNTI, SI-RNTI (system information RNTI), P-RNTI (paging RNTI) or TPC RNTI authorize or carrier wave enables signaling, then the carrier wave reception on a carrier wave on UE enables in M non-designated carrier wave a carrier wave or not in the set of M carrier wave.The operate time of enabling the carrier wave reception on non-designated carrier wave can be implicit expression, such as, x subframe after receiving respective signal from eNB, or can explicitly instruction in the signaling messages.In a particular embodiment, x can be 0.
At place's operate time, UE enters effective time on non-designated carrier wave.Note, if the carrier wave that have disabled specific carriers receives, then UE can stop monitoring PDCCH for this carrier wave, and no matter PDCCH sends on the carrier wave identical from PDSCH Resourse Distribute or on different carrier waves.In one embodiment, if the carrier wave that have disabled specific carriers receives, then UE can stop monitoring the PDCCH be associated with this carrier wave, and the PDCCH no matter associated sends at this carrier wave or on different carrier waves.
If UE is instructed to the carrier wave enabled on non-designated carrier wave and receives, then UE can before operate time, the control information that non-designated carrier wave is corresponding with this is sent, such as CQI (CQI), precoding matrix indicators (PMI), order designator (RI) and sounding reference symbol (SRS) in specific uplink carrier wave or the uplink carrier that is associated with the non-designated carrier wave of down link.Such as, as shown in reference to Figure 20, eNB 2010 determines activationary time (as shown in arrow 2030), and provides the control information (as shown in arrow 2040) for carrier wave configuration at the forward direction UE 2020 of activationary time.
In addition, when the carrier wave forbidding specific carriers receives, UE can stop sending the uplink control information corresponding with this specific carriers to eNB.Such as, as shown in figure 20, have disabled carrier wave by certain signaling receive (as shown in arrow 2050) or operate (as shown in arrow 2055) for the DRX of this carrier wave.When forbidding carrier wave and receiving, the transmission (as shown in arrow 2060) on same forbidding carrier wave.In one embodiment, only during the effective time of non-designated carrier wave, the uplink control information corresponding with non-designated carrier wave is sent to eNB.In another embodiment, control information comprises the control information of the subset for all N number of carrier waves or N number of carrier wave, the control information of such as combining.Just this control information is sent, such as " the single report for all carrier waves " via the uplink carrier of association during the effective time of only meaning designated carrier in office.
Foregoing is set forth below about each embodiment.These embodiments also do not mean that restrictive, and can individually, in conjunction with other embodiments or to those skilled in the art after understanding of the disclosure apparent other alternatives various use together.
1. explicit startup, separately drx-InactivityTimer (drx inactivity timer)
In a first embodiment, during the effective time of the designated carrier of association, the carrier wave enabled on non-designated carrier wave by eNB signaling is received.At the drx-InactivityTimer of place's startup operate time for non-designated carrier wave.Drx-InactivityTimer is restarted when non-designated carrier wave receives new PDSCH grouping.During the effective time of non-designated carrier wave, also keep drx-RetransmissionTimer (drx retransmission timer).When the previous transmission for corresponding HARQ instance process grouping can expectability retransmit time, the time place the earliest starts for the drx-RetransmissionTimer of HARQ procedure.
When correctly receiving the maximum times dividing into groups or reached re-transmission for HARQ procedure, forbid the drx-RetransmissionTimer for HARQ procedure.
When carrier wave drx-InactivityTimer or drx-RetransmissionTimer just operationally, under non-designated carrier wave is remained on effective time by UE.Any time place during the effective time of non-designated carrier wave, the carrier wave that eNB can be forbidden on non-designated carrier wave by signaling command UE receives.
When drx-InactivityTimer and drx-RetransmissionTimer does not have operationally, the carrier wave on forbidding carrier wave receives.
With reference now to Fig. 2.In fig. 2, the designated carrier 200 be associated with non-designated carrier wave 205 is shown to have attribute like the carrier-class with Fig. 1.In this, similar reference symbol is used.
Designated carrier 200 has the time place of OnDuration 122, OnDuration 122 shown in reference symbol 120 and starts.Then, the time of UE shown in arrow 130 is in designated carrier receives and sends corresponding last PDCCH message with new data, and the time point place shown in arrow 130 restarts drx-InactivityTimer 132.In addition, when the HARQ retransmission timer expires for downlink HARQ process, the drx-RetransmissionTimer for identical downlink HARQ process 140 is started.This waits for checking the timer whether received during HARQ retransmits for UE.
As shown in Figure 1, expire in the time place of drx-InactivityTimer 132 shown in arrow 134.This be drx-RetransmissionTimer 142 expire after.At this some place, designated carrier 200 enters DRX mode.Arrow 136 shows the effective time that UE monitors the PDCCH on designated carrier.
If be configured with short DRX cycle, then designated carrier 200 gets back to effective model 110 after the short DRR cycle 150 expires.On the contrary, if be configured with long DRX cycle, then designated carrier 200 gets back to effective model 110 after long DRX cycle 152 expires.
At certain time point place, eNB recognize in addition data to send to UE and send signal starting second (or subsequently) component carrier.As the result of the message shown in arrow 210, start non-designated carrier wave 205, receive with the carrier wave enabled on component carrier.
According to the first embodiment, drx-InactivityTimer is associated with component carrier.Drx-InactivityTimer can have pre-configured length, or the length of drx-InactivityTimer can carry out signaling by eNB.
When receiving signal or corresponding operate time (shown in arrow 210), non-designated carrier wave 205 enters effective model, and the carrier wave that namely UE starts on non-designated carrier wave 205 receives.During effective model, as indicated by the arrow 220, non-designated carrier wave receives last new PDSCH grouping.At this some place, restart drx-InactivityTimer 222.In addition, after the HARQ RTT time, drx-RetransmissionTimer 224 is started.
In the figure 2 example, receive HARQ retransmit and stop drx-RetransmissionTimer 224.
When drx-InactivityTimer 222 expires, as shown in reference symbol 230, non-designated carrier wave 205 is forbidden it and is received.At this some place, eNB can pass through designated carrier 200 signaling of association, to reactivate the reception on non-designated carrier wave 205 in the future at certain time point place.
2. explicit signaling, without drx-InactivityTimer
In another embodiment, during the effective time of the designated carrier of association, the carrier wave enabled on non-designated carrier wave by eNB signaling is received.The drx-InactivityTimer be separated is not kept for non-designated carrier wave.At place's operate time, the carrier wave that UE enables on non-designated carrier wave that eNB distributes receives.During the effective time of designated carrier, the carrier wave that UE continues to enable on non-designated carrier wave receives, unless received explicit signaling from eNB to forbid carrier wave reception non-designated carrier wave order UE.Because HARQ retransmission processes occurs independently between the designated carrier and each non-designated carrier wave of association, therefore, each in these carrier waves keeps himself drx-RetransmissionTimer for each its downlink HARQ process.In one embodiment, at the drx-InactivityTimer for designated carrier or for designated carrier or at least one in the drx-RetransmissionTimer of any non-designated carrier wave be associated with designated carrier just operationally, under designated carrier should remain on effective time.In another embodiment, even if one or more in the drx-RetransmissionTimer of the non-designated carrier wave be associated with designated carrier still run, designated carrier also can enter DRX.
With reference now to Fig. 3.In figure 3, the designated carrier 200 be associated with non-designated carrier wave 305 is similar with the designated carrier 200 of Fig. 2.
The non-designated carrier wave 305 be associated with designated carrier 200 is only configured with a drx-RetransmissionTimer for each in its downlink HARQ process.
As shown in Figure 3, eNB sends explicit signaling to UE and activates non-designated carrier wave 305 to indicate UE.This is illustrated by arrow 310.Then, non-designated carrier wave enters time period effective time one, and this time period was determined by the effective time 136 of the designated carrier 200 associated, or as mentioned above, can be determined by drx-RetransmissionTimer.
Assuming that drx-RetransmissionTimer runs, then at 134 places, designated carrier 200 enters DRX.Meanwhile, UE forbids the reception on non-designated carrier wave 305.
Second effective time section, as depicted by arrow 320, UE receives the eNB signaling for non-designated carrier wave 305, to enable reception.As indicated by the arrow 322, this reception is forbidden by the explicit eNB signaling to UE subsequently.
3. the mixing of the embodiment of Fig. 2 and Fig. 3
With reference now to Fig. 4.DRX operation above described in Fig. 2 and Fig. 3 can for same UE, on identical or different non-designated carrier wave, occur at different time.When the eNB signaling UE carrier wave enabled for non-designated carrier wave receives, the drx-InactivityTimer whether eNB can indicate UE to keep for this non-designated carrier wave.In one embodiment, if eNB indicate UE keep drx-InactivityTimer, then follow-up be above about described in Fig. 2 DRX operation.Otherwise, follow-up be above about described in Fig. 3 DRX operation.In other embodiments, signaling can be anti-, and can use drx-InactivityTimer, unless explicit signaling indicates contrary content.
Fig. 4 shows the signaling of activation two non-designated carrier waves.Also namely, non-designated carrier wave 205 is activated by the message shown in arrow 210.In the message of arrow 210, eNB signaling should use drx-InactivityTimer.Such as, this signaling can utilize individual bit mark to indicate.In other embodiments, this signaling can comprise the value for drx-InactivityTimer.Other signalings of drx-InactivityTimer should be used also to be fine.
Based on the message of arrow 210, non-designated carrier wave 205 is according to continuing about shown in Fig. 2 above.When drx-InactivityTimer 222 expires, non-designated carrier wave 205 continues according to shown in reference symbol 230, to forbid reception.
Similarly, as shown in reference symbol 310, the non-designated carrier wave 305 of signaling activates.This signaling does not provide drx-InactivityTimer or should use the instruction of drx-InactivityTimer.In this, the effective time of non-designated carrier wave 305 is after the effective time 136 of the designated carrier 200 of association.If drx-RetransmissionTimer runs, then may there is exception.
Similarly, can as depicted by arrow 320, provide explicit signaling to enable the reception on non-designated carrier wave 305, and as indicated by the arrow 322, explicit signaling can also be provided to forbid the reception on non-designated carrier wave 305.
4. inherent activation
In another embodiment, when the OnDuration of designated carrier starts, the carrier wave that UE enables on non-designated carrier wave that the eNB that is associated with designated carrier distributes receives.During the effective time of the designated carrier of association, the carrier wave that UE continues to enable on non-designated carrier wave receives, unless received explicit signaling from eNB to forbid carrier wave reception non-designated carrier wave order UE.
Because HARQ retransmission processes occurs independently between designated carrier and non-designated carrier wave, therefore, each in these carrier waves keeps himself drx-RetransmissionTimer for each its HARQ procedure.At the drx-InactivityTimer for designated carrier or for designated carrier or at least one in the drx-RetransmissionTimer of any non-designated carrier wave be associated with designated carrier just operationally, under designated carrier remains on effective time.
With reference now to Fig. 5.In Figure 5, the designated carrier 200 be associated with non-designated carrier wave 505 is with similar above with reference to the designated carrier 200 described in Fig. 2-4.
About non-designated carrier wave 505, the time place shown in 510, the effective time for non-designated carrier wave 505 starts, and the time shown in the time shown in 510 with reference symbol 120 is corresponding.Similarly, as indicated by arrows 134, when drx-InactivityTimer 132 expires, as shown in reference symbol 512, non-designated carrier wave 505 also enters DRX.
Subsequently, when short DRX cycle 150 expires, as shown in reference symbol 520, designated carrier 200 and the non-designated carrier wave 505 be associated with designated carrier 200 all enter effective time.
In the example of hgure 5, as arrow 522 provide, the explicit signaling from eNB to UE makes UE forbid reception non-designated carrier wave 505, and enters DRX.But in an embodiment of Fig. 5, next cycle effective time on designated carrier 200 also makes the non-designated carrier wave 505 be associated with designated carrier 200 enter effective time.
As mentioned above, based on the drx-RetransmissionTimer run on non-designated carrier wave 505, effective time 136 can be extended.
5. inherent activation, inactivity timer
In another embodiment, with similar about the embodiment described in Fig. 5 above, when the OnDuration of designated carrier starts, the carrier wave that UE enables on non-designated carrier wave that the eNB that is associated with designated carrier distributes receives.In certain embodiments, the carrier wave can enabled on the multiple non-designated carrier wave that is associated with designated carrier receives.
In addition, drx-InactivityTimer is kept for non-designated carrier wave.When the carrier wave enabling non-designated carrier wave when the OnDuration of the designated carrier associated starts receives, start drx-InactivityTimer.When receiving new PDSCH grouping on non-designated carrier wave, restart drx-InactivityTimer.Also during the effective time of non-designated carrier wave, keep drx-RetransmissionTimer.When the previous transmission for corresponding HARQ instance process grouping can expectability retransmit time, the time place the earliest starts for the drx-RetransmissionTimer of HARQ procedure.When correctly receiving the maximum times dividing into groups or reached re-transmission for HARQ procedure, forbid the drx-RetransmissionTimer for HARQ procedure.
When drx-InactivityTimer or drx-RetransmissionTimer just operationally, under non-designated carrier wave remains on effective time.Any time place during the effective time of non-designated carrier wave, the carrier wave that eNB can be forbidden on non-designated carrier wave by signaling command UE receives.
In one embodiment, designated carrier can postpone to enter DRX from effective time, until all inactivity timer on the non-designated carrier wave be associated with designated carrier and DRX retransmission timer all expired.
With reference to figure 6, the designated carrier 200 be associated with non-designated carrier wave 605 is similar with above-mentioned designated carrier.
Non-designated carrier wave 605 is activated at OnDuration 122 place of the designated carrier 200 of association.Particularly, as shown in reference symbol 610, effective time starts at time 120 place identical with the designated carrier 200 associated.
As indicated by arrows 620, when receiving last new PDSCH and divide into groups on non-designated carrier wave, the drx-InactivityTimer 622 for this non-designated carrier wave is restarted.
As shown in reference symbol 630, when drx-InactivityTimer 622 expires, non-designated carrier wave 605 proceeds to the DRX time period.
Subsequently, as shown in reference symbol 640, expire simultaneously with the short DRX cycle 150 of the designated carrier 200 associated, non-designated carrier wave 605 enters effective time.
Receive explicit message 642 from eNB, non-designated carrier wave 605 is forbidden and receives.But in one embodiment, the follow-up OnDuration at designated carrier 200 place of association makes non-designated carrier wave 605 enter effective time.
Also drx-RetransmissionTimer 624 can be used to extend the effective time of non-designated carrier wave 605.
6. regulation is for the OnDuration timer of non-designated carrier wave
In another embodiment, eNB can by RRC signaling or MAC CE or other signaling methods, to the OnDuration timer of UE signaling for non-designated carrier wave.OnDurationTimer is supplementing drx-RetransmissionTimer.
With similar above with reference to the embodiment described in Fig. 5, when the OnDuration of the designated carrier associated starts, the carrier wave that UE enables on the non-designated carrier wave of eNB distribution receives.UE is also at this time place's startup OnDurationTimer.
Also during the effective time of non-designated carrier wave, keep drx-RetransmissionTimer.When the previous transmission for corresponding HARQ instance process grouping can expectability retransmit time, the time place the earliest starts for the drx-RetransmissionTimer of HARQ procedure.When correctly receiving the maximum times dividing into groups or reached re-transmission for HARQ procedure, forbid the drx-RetransmissionTimer for HARQ procedure.
When OnDurationTimer is running and the designated carrier associated is in effective time or when the drx-RetransmissionTimer for non-designated carrier wave just operationally, under non-designated carrier wave is remained on effective time by UE.In another embodiment, when OnDurationTimer just operationally or when drx-RetransmissionTimer just operationally, under non-designated carrier wave is remained on effective time by UE, and whether the designated carrier no matter associated is in effective time.In addition, in one embodiment, any time place during the effective time of non-designated carrier wave, the carrier wave that eNB can be forbidden on non-designated carrier wave by signaling command UE receives.
With reference to figure 7, the designated carrier 200 be associated with non-designated carrier wave 705 is similar with above-mentioned designated carrier 200.
After non-designated carrier wave 705 follows the activation of the effective time of the designated carrier in association.Therefore, with similar shown in the reference symbol 120 for the designated carrier 200 associated, as shown in reference symbol 710, non-designated carrier wave 705 enters effective model.
In the embodiment of Fig. 7, expire in the time place of OnDurationTimer 720 shown in reference symbol 722.At this some place, UE forbids the reception on non-designated carrier wave 705.
When such as shown in reference symbol 110, when the designated carrier 200 of association gets back to effective model, locate to forbid the reception on non-designated carrier wave 705 terminating the time shown in corresponding reference symbol 730 with short DRX cycle 150.
Subsequently, receive explicit signaling, to forbid non-designated carrier wave 705.Arrow 732 shows explicit signaling, non-designated carrier wave 705 is forbidden and receives.
With reference to figure 8.In an alternative embodiment, the OnDurationTimer 820 of Fig. 8 was set to for the relatively long time period.
In the embodiment in fig. 8, non-designated carrier wave 705 the time 710 place enter effective time.This corresponds to as shown in reference symbol 120, is activated by the designated carrier 200 of association and enters effective time.
But contrary with the embodiment of Fig. 7, in the embodiment in fig. 8, OnDurationTimer820 did not expire before effective time 136, DRX mode was got back to by end at the designated carrier 200 of association.In this case, UE located to forbid the reception on non-designated carrier wave 705 with terminate the effective time 136 of the designated carrier 200 associated the time shown in corresponding reference symbol 822.
The remaining point of Fig. 8 is corresponding with the point in Fig. 7.
Therefore, according to above-described embodiment, OnDurationTimer can force UE to forbid reception on non-designated carrier wave 705 before effective time 136 of the designated carrier 200 of association expires.On the contrary, if expired before the OnDurationTimer 820 of non-designated carrier wave 705 expires the effective time 136 of the designated carrier 200 of association, then this can make UE forbid reception on non-designated carrier wave 705
7.signal
notice OnDurationTimer and drx-InactivityTimer
In another embodiment, except drx-RetransmissionTimer and drx-InactivityTimer, eNB can pass through RRC signaling, MAC CE or other signalings, also to the OnDurationTimer of UE signaling for non-designated carrier wave.Similar with above-mentioned Fig. 6, when the OnDuration on the designated carrier associated starts, the carrier wave that UE enables on the non-designated carrier wave of eNB distribution receives.Now UE also starts OnDurationTimer and drx-InactivityTimer.
Drx-InactivityTimer is restarted when receiving new PDSCH grouping on non-designated carrier wave.Also during the effective time of non-designated carrier wave, keep drx-RetransmissionTimer.When the previous transmission for corresponding HARQ instance process grouping can expectability retransmit time, the time place the earliest starts for the drx-RetransmissionTimer of HARQ procedure.When correctly receiving the maximum times dividing into groups or reached re-transmission for HARQ procedure, forbid the drx-RetransmissionTimer for HARQ procedure.
When OnDurationTimer is running and the designated carrier associated is in effective time or when drx-InactivityTimer running or drx-RetransmissionTimer just operationally, under non-designated carrier wave is remained on effective time by UE.In another embodiment, when OnDurationTimer just operationally or when drx-InactivityTimer running or drx-RetransmissionTimer just operationally, under non-designated carrier wave is remained on effective time by UE, and whether the designated carrier no matter associated is in effective time.
Any time place during the effective time of non-designated carrier wave, the carrier wave that eNB can be forbidden on non-designated carrier wave by signaling command UE receives.
With reference now to Fig. 9.In fig .9, the designated carrier 200 be associated with non-designated carrier wave 905 is similar with above-mentioned designated carrier.
About non-designated carrier wave 905, eNB to the value of UE signaling OnDurationTimer 912 and drx-InactivityTimer 922.
About Fig. 9, according to above about the mode that the mode described in Fig. 7 is similar, the effective time 910 of non-designated carrier wave 905 can be the value of OnDurationTimer 912.In addition, can extend based on drx-InactivityTimer 922 effective time 910.When as depicted by arrow 920, when receiving last new PDSCH grouping, drx-InactivityTimer restarts and continues operation, until as shown in reference symbol 930, the time that drx-InactivityTimer expires, at this time point place, non-designated carrier wave 905 is forbidden and is received.
In other embodiments, drx-RetransmissionTimer 924 can extend effective time 910.
Time place shown in reference symbol 940, OnDurationTimer 912 is reset, and non-designated carrier wave 905 enters effective time, and this time is corresponding to the end of the short DRX cycle 150 of the designated carrier 200 for association.As shown in arrow 942, provide explicit signaling to forbid non-designated carrier wave 905 to UE.
In other embodiments, if drx-InactivityTimer922 or drx-RetransmissionTimer 924 on non-designated carrier wave 905 is still in operation, then the effective time 136 of Fig. 9 can be extended.Alternatively, non-designated carrier wave 905 can be forced to forbid in end's effective time 136 and receive, and no matter whether drx-InactivityTimer 922 or drx-RetransmissionTimer924 expires.
In another alternative embodiment, the effective time 136 of the designated carrier 200 that can exceed association effective time 910 of non-designated carrier wave 905.
8.drx-FollowDesignatedTimer
In another embodiment, eNB can pass through RRC signaling, MAC CE or other communication modes, to " drx-FollowDesignatedTimer " of UE signaling for non-designated carrier wave.In addition, can signaling drx-RetransmissionTimer.
By such as RRC signaling " statically " or can dynamically configure drx-FollowDesignatedTimer value by MAC CE.During the effective time of designated carrier, eNB can be received by the carrier wave of signaling command UE on the specific action time, the non-designated carrier wave that is associated with designated carrier was enabled at place.For the situation of the dynamic-configuration of drx-FollowDesignatedTimer, the signaling that the carrier wave enabling non-designated carrier wave receives comprises drx-FollowDesignatedTimer value.At place's operate time, UE starts drx-FollowDesignatedTimer.
Also during the effective time of non-designated carrier wave, keep drx-RetransmissionTimer.When the previous transmission for corresponding HARQ instance process grouping can expectability retransmit time, the time place the earliest starts for the drx-RetransmissionTimer of HARQ procedure.When correctly receiving the maximum times dividing into groups or reached re-transmission for HARQ procedure, forbid the drx-RetransmissionTimer for HARQ procedure.When drx-FollowDesignatedTimer just operationally, UE is only when the designated carrier associated is in effective time or under non-designated carrier wave is just operationally just remained on effective time by drx-RetransmissionTimer.When drx-FollowDesignatedTimer expires, if drx-RetransmissionTimer also expires, then the carrier wave that UE is forbidden on non-designated carrier wave receives, and regardless of effective time of the designated carrier associated.
In a specific embodiment, drx-FollowDesignatedTimer has several long DRX cycle or short DRX cycle on the duration.This means, the effective time of non-designated carrier wave will follow several long DRX cycle or short DRX cycle after the effective time of the designated carrier of association, and the carrier wave then forbidden on non-designated carrier wave receives.
With reference now to Figure 10.In Fig. 10, the designated carrier 200 be associated with non-designated carrier wave 1005 is similar with above-mentioned designated carrier.
There is provided explicit signaling 1008 to start non-designated carrier wave 1005.
Non-designated carrier wave 1005 has been signaled for a very short time drx-FollowDesignatedTimer1020.As mentioned above, this signaling can comprise pre-configured value, or can have dynamic value.
Non-designated carrier wave 1005 is followed after the designated carrier 200 of association in drx-FollowDesignatedTimer 1020 valid period.Therefore, the time place shown in reference symbol 1010, non-designated carrier wave 1005 enters effective model, and the time place shown in reference symbol 1022, non-designated carrier wave 1005 enters DRX mode or forbidding receives.This time shown in reference symbol 1022 is expired corresponding with the drx-InactivityTimer's 132 on the designated carrier 200 associated.
Similarly, the short expired place of DRX cycle 150 in the embodiment in figure 10, as shown in reference symbol 1030, non-designated carrier wave 1005 gets back to effective time.
Expire at drx-FollowDesignatedTimer 1020 and locate, non-designated carrier wave 1005 is forbidden and is received, until receive explicit signaling again.
In certain embodiments, drx-FollowDesignatedTimer 1020 can be used in conjunction with drx-InactivityTimer.
LTE Rel 8 specification (such as 3GPP TS 36.321) can be supplemented to consider above-described embodiment.Example for the extention of this specification of designated carrier can be:

After attention: UE can select to receive the PDCCH of the new transmission (UL or DL) of instruction alternatively in the last subframe of effective time, on PUCCH, do not send CQI/PMI/RI report and/or SRS sends reaching in 4 subframes.Select on PUCCH, do not send CQI/PMI/RI report and/or SRS sends and is not suitable for the subframe that OnDurationTimer running.
For non-designated carrier wave, be implemented in above-described embodiment, for each carrier wave (wherein M defines as mentioned above) in M non-designated carrier wave, the carrier wave implicitly can enabled on this carrier wave in Onduration startup place of the designated carrier be associated with non-designated carrier wave receives, i.e. pattern 1; Or, can by the explicit eNB signaling to UE during the effective time of the designated carrier of association, the carrier wave that explicitly is enabled on this carrier wave receives, i.e. pattern 2.These two kinds of patterns can be configured for each in M non-designated carrier wave by eNB and to UE signaling (such as, by RRC signaling).In mode 2, during the effective time of designated carrier, eNB can by the control signal of transmission on designated carrier or on one of other N number of component carriers (such as, RRC signaling, PDCCH or MAC Control Element), order UE enables another non-designated component carrier of being associated with designated carrier (such as, carrier wave i) on carrier wave receive, wherein N defines as mentioned above.

specify and non-designated carrier wave on short and long DRX cycle
In another embodiment, whole DRX parameter sets can all be configured for designated carrier and non-designated carrier wave.The intelligent scheduling at eNB place effectively can utilize the short and long DRX cycle on appointment and non-designated carrier wave.
When being also configured with short DRX cycle, if UE receives the Resourse Distribute (be only new data, instead of HARQ retransmitting) for new data recently, then UE operates in short DRX cycle substantially.After not receiving new data resource and distributing a special time period, UE is switched to long DRX cycle after drxShortCycleTimer expires.UE continues to use long DRX cycle, distributes until receive another new data resource on PDCCH.
If each non-designated carrier wave is configured to utilize short and long DRX cycle to operate, then UE can adapt to happen suddenly business scenario and without any need for explicit signaling.The UE receiving mass data will make its all carrier wave (comprise specify and non-designated) utilize short DRX cycle to operate.If data volume declines, then intelligent eNB all data of will only dispatch on designated carrier for UE.This will make designated carrier continue to utilize short DRX cycle to operate, then non-designated carrier wave will automatically switch to and use long DRX cycle (distributing because they can not receive any new data resource) after drxShortCycleTimer expires.If the business activity subsequently for UE increases, then non-designated carrier wave will start to be used during OnDuration by eNB again, and automatic switchover is returned short DRX cycle pattern by these non-designated carrier waves.The short DRX cycle of non-designated carrier wave and the boundary alignment of the border of long DRX cycle with the designated carrier associated.
Further expanding of foregoing is: in a special time period, untapped carrier wave (such as, the multiple long DRX cycle length of configuration) can by UE (implicit expression) deexcitation automatically, and need to be reactivated by eNB before the use.
In another embodiment, the implicit expression of the carrier wave at UE place activates is possible.If UE receives the Resourse Distribute of the carrier wave for current forbidding on the PDCCH of association, then should reactivate this carrier wave immediately.As can be appreciated, the Resourse Distribute causing this implicit expression to activate can not be processed, but can process the Resourse Distribute in any future on this carrier wave.
With reference now to Figure 11.In fig. 11, designated carrier 200 operates as mentioned above.
Non-designated carrier wave 1105 is configured with short DRX cycle 1150 and long DRX cycle 1152 independently.When exchanges data starts, non-designated carrier wave 1105 is configured to use short DRX cycle.Therefore, as shown in figure 11, non-designated carrier wave 1105 was followed after designated carrier 200 through effective time.
If do not receive data on non-designated carrier wave 1105 within the duration of short DRX cycle 1150, then as shown in figure 11, non-designated carrier switch is to long DRX cycle 1152.In the example of fig. 11, long DRX cycle 1152 is two double-lengths of short DRX cycle 1150.But this does not also mean that restrictive, because long DRX cycle can be any multiple of short DRX cycle.
Signaling
signaling DRX parameter
As mentioned above, eNB can for UE, and configuration pin is to the DRX parameter of designated carrier and the DRX parameter for M non-designated carrier set.Each in M non-designated carrier wave, DRX parameter sets comprises drx-RetransmissionTimer, can comprise drx-InactivityTimer, can comprise onDurationTimer, and can comprise drx-FollowDesignatedTimer.Each in M non-designated carrier wave, eNB can configure the designated carrier be associated with non-designated carrier wave.Each in M non-designated carrier wave, the carrier wave whether eNB can indicate UE should enable on this carrier wave in OnDuration startup place of the designated carrier of association receives, or only just enables when receiving explicit activation signaling from eNB and receive at the carrier wave of this carrier wave.
In one embodiment, the value of drx-InactivityTimer (if comprising), onDurationTimer (if comprising), drx-RetransmissionTimer is all identical in all component carriers.In this case, the RRC signaling for configuring DRX function does not need to comprise drx-InactivityTimer, onDurationTimer and drx-RetransmissionTimer field for each component carrier.For one of designated carrier, can comprise the value of whole DRX parameter sets in RRC signaling, and the drx-InactivityTimer (if comprising) of the value of the DRX parameter of other designated carriers and other M non-designated component carrier, onDurationTimer (if comprising), drx-RetransmissionTimer are identical with designated carrier.RRC signaling also comprises the drx-FollowDesignatedTimer for the non-designated carrier wave being configured with drx-FollowDesignatedTimer.
In another embodiment, the value for the DRX parameter of different designated carrier is different.Drx-InactivityTimer (if comprising), onDurationTimer (if comprising), the drx-RetransmissionTimer of non-designated carrier wave are identical with the designated carrier associated.In this case, RRC signaling comprises the whole DRX parameter sets for each designated carrier.Identical with the designated carrier that it associates for each drx-InactivityTimer (if comprising) in M non-designated component carrier, onDurationTimer (if comprising), drx-RetransmissionTimer.
In another embodiment, the value of drx-InactivityTimer (if comprising), onDurationTimer (if comprising), drx-RetransmissionTimer and drx-FollowDesignatedTimer (if comprising for non-designated carrier wave) is different for different component carriers.In this case, RRC signaling comprises the whole DRX parameter sets for designated carrier, and for the DRX parameter sets of each simplification in M other component carriers, i.e. drx-InactivityTimer (if comprising), onDurationTimer (if comprising), drx-RetransmissionTimer and drx-FollowDesignatedTimer (if comprising for non-designated carrier wave).
In another embodiment, drx-InactivityTimer (if comprising), the onDurationTimer (if comprising) of some component carriers are identical with the designated carrier that the value of drx-RetransmissionTimer associates with it, and the drx-InactivityTimer of some other component carriers (if comprising), onDurationTimer (if comprising) and the value of drx-RetransmissionTimer and the different of its designated carrier.In this case, RRC signaling comprises the whole DRX parameter sets for designated carrier, and for the DRX parameter sets of the simplification of some in M component carrier, i.e. drx-InactivityTimer (if comprising), onDurationTimer (if comprising) and drx-RetransmissionTimer and for the drx-FollowDesignatedTimer of some be configured with in M the component carrier of drx-FollowDesignatedTimer.
In another embodiment, the DRX parameter of all non-designated carrier waves is configured to identical value.In this case, RRC signaling comprises the DRX parameter sets for whole DRX parameter sets of designated carrier and the simplification for all M other component carriers, i.e. drx-InactivityTimer (if comprising), onDurationTimer (if comprising), drx-RetransmissionTimer and drx-FollowDesignatedTimer (if comprising).
Table 1 below illustrates the example of the field of the different embodiment of support that corresponding RRC signaling comprises.Shown signaling field and form also do not mean that restriction.One skilled in the art would recognize that and considering in situation of the present disclosure, other signaling fields and form are also fine.
The example of the DRX parameter that table 1:RRC signaling comprises
the signaling of enabling/forbidding carrier wave reception from eNB to UE
ENB can pass through RRC signaling or MAC CE, and even via particular downlink control information (DCI) form on PDCCH (that is, layer 1 signaling), order UE receives with the carrier wave enabled or disabled on component carrier.RRC signaling or MAC CE or PDCCH can only on designated carrier, transmission or any carrier wave in N number of component carrier send, and wherein N defines as mentioned above.Send in RRC signaling, MAC CE or PDCCH for enabling in the signaling message that carrier wave on component carrier receives, can comprise a field to indicate this component carrier is designated carrier or non-designated carrier wave.
With reference now to Figure 12.Figure 12 shows the example of " carrier wave receives and enables/disable command MAC Control Element " 1200 for enabling/forbidding the carrier wave reception on carrier wave that eNB sends to UE, has explicit operate time.New MAC Control Element 1200 can use one of reserved DL LCID (logic channel ID) for DL-SCH (downlink sharied signal channel) shown in the table 6.2.1-1 of 3GPP TS36.321." DL " 1205 is bit fields, that specify in order to indication carrier wave or non-designated carrier wave." E/D " 1210 is bit fields, enables or forbids carrier wave receive in order to indicate this order." carrier index " 1220 enable/forbid physics or the logical carrier index of the carrier wave that carrier wave receives.If " E/D " 1210 is set to forbidding, carrier wave receives, then the value of " DS " 1205 can be set to predefined value, and UE ignores this value.Another embodiment is: this order only affects the carrier wave that have sent " carrier wave receives and enables/disable command MAC Control Element " 1200 thereon.Such as, if receive the MAC CE of forbidding carrier wave reception on carrier wave #3, then carrier wave #3 will forbid carrier wave reception.The operate time should enabling/forbid the carrier wave reception on carrier wave is defined by next radio frames, wherein 4 least significant bits (LSB) of System Frame Number (SFN) are equal to " operate time (LSB of SFN) " 1230, and the subframe in this radio frames with this subframe numbers is equal to " operate time (sub-frame offset) " 1240.
Another of operate time is alternative is define relative time offset.One skilled in the art will recognize that in some cases, the fixed reference timing determining relative time offset may be difficult to, because MAC CE sends may relate to HARQ re-transmission.A kind of possible mode setting up the fixed reference time is: when receiving HARQ ACK on UL, eNB can derive UE before 4ms, receive corresponding MAC CE, because in one embodiment, HARQ feedback transmission is the 4ms place after the transmission block of correspondence receives.
4 LSB of SFN allow the HARQ of nearly 16 radio frames or 160ms to retransmit to attempt, successfully to receive MAC CE and to eNB feedback acknowledgment at UE.MAC ACK CE (being called " carrier wave receives and enables/forbid ACKMAC control unit ") is defined so that UE confirms to receive " carrier wave receives and enables/disable command MAC Control Element " in up link (UL).Explicit confirmation agreement allows eNB to confirm: before sending PDSCH data to UE on the assigned carrier, UE successfully receives " carrier wave receives and enables/disable command MAC Control Element " 1200.
Usually, only in RRC level, control signal is confirmed.But this specific MAC control signal may have long-term importance, the confirmation therefore with certain form is very important.RRC signaling is fine, but in certain embodiments, RRC signaling may be too slow for required object, or may cause too large expense compared with the signaling of the MAC level proposed at this.
" carrier wave receives and enables/disable command MAC Control Element " 1200 another alternatives confirmed use HARQ feedback to receiving.When comprising the transmission block of MAC CE to UE transmission, eNB will monitor corresponding UL HARQ feedback.When receiving corresponding HARQ instance ACK in UL, eNB thinks: UE successfully receives " carrier wave receive enable/disable command MAC Control Element " 1200.
With reference now to Figure 13, Figure 13, show the example of " carrier wave receives and enables/forbid ACK MAC Control Element " 1300." carrier index " 1310 is that carrier wave receives the physics or logical carrier index enabling/receive and order the carrier wave be identified.This new MAC CE 1300 can use one of reserved UL LCID value for UL-SCH shown in the table 6.2.1-2 of 3GPP TS 36.321.
With reference now to Figure 14, Figure 14, show another format sample of the MAC Control Element that the carrier wave for enabling or disabling on carrier wave receives.Here, binary marks 1410,1412,1414 and 1416 is for optionally enabling or disabling maximum nearly 4 carrier waves.It is designated carrier or non-designated carrier wave that field 1411,1413,1415,1417 is used to indicate 1410,1412, the 1414 and 1416 each carrier waves indicated respectively.If CI field is set to forbidding, carrier wave receives, then the respective value of DS field can be set to predefined value, and UE ignores this field.
As recognized, in an embodiment with designated carrier and four non-designated carrier waves, a UE can be polymerized this five carrier waves.A carrier wave is the current designated carrier be in effective time, and four non-designated carrier waves leave binary marks 1410,1412,1414 and 1416 for.In addition, in one embodiment, simply the carrier index for any unappropriated carrier wave can be used as reserved bit or filling bit.
Such as, 0 value instruction of binary marks 1410: corresponding non-designated carrier wave should be forbidden, and 1 value instruction: corresponding non-designated carrier wave should be enabled.Similarly, binary marks 1412,1414 and 1416 can be set.Its corresponding binary marks is only set to and value identical before by any carrier wave continuing to remain on current state.Such as, if current being activated of carrier wave 1 and 2 and carrier wave 3 and 4 is current disabled, then the binary value 00001010 of the first byte 1420 of MAC Control Element will order UE (a) to keep enabling carrier wave 1, (b) forbidding carrier wave 2, c () enables carrier wave 3, and (d) keeps forbidding carrier wave 4.Notification action time field is carried out according to mode identical as mentioned above.
Figure 15 comprises and receives to UE the corresponding format sample that the confirmation MAC CE 1500 that MAC Control Element confirms was enabled/forbidden to the carrier wave shown in Figure 14.With CI
1, CI
2, CI
3, CI
4corresponding binary marks 1510,1512,1514 with 1516 value be set to previous corresponding binary marks value in " carrier wave receives and enables/disable command MAC Control Element " 1400 of Figure 14 1410,1412,1414 identical with 1416.
Figure 14 is with the advantage of the MAC CE form of 15: can be enabled by identical MACCE simultaneously and/or forbid multiple carrier wave, and does not need to send multiple MAC Control Element (thus representing additional signaling consumption) to realize identical object.
If also wish optionally enable and forbid uplink carrier, then above-mentioned MACCE is carried out the expansion as shown in the MAC Control Element 1600 in Figure 16, to process maximum nearly 4 downlink carriers and four uplink carriers.A bit for each carrier wave is enabled/is forbidden field and operates according to previous discussed mode.Particularly, downlink carrier mark 1610,1612,1614 and 1616 controls four downlink carriers, and uplink carrier mark 1620,1622,1624 and 1626 controls the activation/deactivation of four uplink carriers.
Figure 17 shows the form enabling/forbid the corresponding MAC CE 1700 that MACCE 1600 confirms for receiving the carrier wave shown in Figure 16 to UE.Therefore, downlink carrier mark 1710,1712,1714 and 1716 corresponds to downlink carrier mark 1610,1612,1614 and 1616, and uplink carrier mark 1720,1722,1724 and 1726 corresponds to uplink carrier mark 1620,1622,1624 and 1626.
Gather for the MAC CE proposed in Figure 14 and 15, the content of the confirmation control unit in Figure 17 is the mirror image enabling/forbid the first byte of payload of control unit in Figure 16.
As recognized, above-described embodiment can be implemented on any UE.Below in conjunction with Figure 18, a schematic UE is described.This does not also mean that restriction, but is provided for schematic object.
Figure 18 shows the block diagram of the UE that can use together with the embodiment of the apparatus and method of the application.Typically, mobile device 1800 is the two-way wireless communication device with voice or its communication ability.According to provided exact function, wireless device can be called as such as data-message transmission equipment, bidirection pager, wireless e-mail devices, the cell phone with data-message transmittability, wireless the Internet appliance, mobile device or data communications equipment.
If enable UE 1800 for two-way communication, it will in conjunction with communication subsystem 1811, comprise receiver 1812 and transmitter 1814, and the assembly be associated, the such as processing module of one or more (normally embedding or built-in) antenna element 1816 and 1818, local oscillator (LO) 1813 and such as digital signal processor (DSP) 1820.To understand as technical field of communication personnel, the particular design of communication subsystem 1811 will be intended to according to equipment the communication network that wherein carries out operating.
According to the type of network 1819, network insertion demand also will change.Such as, in order to operate on LTE or LTE-A network, LTE UE may need subscriber identity module (SIM) to block.SIM interface 1844 is similar to the draw-in groove that SIM card can be inserted into or eject as tape or pcmcia card usually.SIM card can keep many key configuration 1851, and the out of Memory 1853 of such as mark and subscriber-related information.
When completing required network registration or activation, UE 1800 can be sent and receiving communication signal by network 1819.As shown in figure 18, network 1819 can be made up of the multiple antennas communicated with UE.These antenna is connected to eNB 1870 successively.
Antenna 1816 inputs to receiver 1812 by the signal that communication network 1819 receives, this receiver can perform general receiver function, as signal amplification, down-conversion, filtering, Channel assignment etc., and modulus (A/D) conversion in the example system shown in Figure 18.The A/D conversion of received signal allows the more complicated communication function of the demodulation code that such as will perform in DSP 1820.In a similar fashion, process the signal that will transmit, comprise such as by modulation and the coding of DSP1820, and input to transmitter 1814 and carry out digital-to-analogue conversion, up-conversion, filtering, amplification and transmitted on communication network 1819 by antenna 1818.DSP 1820 not only process communication signals, but also provide Receiver And Transmitter to control.Such as, the gain of the signal of communication put in receiver 1812 and transmitter 1814 can be controlled adaptively by the automatic gaining controling algorithm realized in DSP 1820.
Typically, UE 1800 comprises the processor 1838 of control appliance integrated operation.The communication function comprising data and voice communication is performed by communication subsystem 1811.Processor 1838 also carries out with miscellaneous equipment subsystem alternately, such as other communication subsystems 1840 such as display 1822, flash memory 1824, random access memory (RAM) 1826, auxiliary I/O (I/O) subsystem 1828, serial ports 1830, one or more keyboard or keypad 1832, loud speaker 1834, microphone 1836, such as short-range communication subsystem and refer generally to any miscellaneous equipment subsystem being decided to be 1842.Serial ports 1830 can comprise other ports that USB port or one of ordinary skill in the art know.
Some in subsystem shown in Figure 18 perform the function relevant to communication, but other subsystem can provide the function on " resident " or equipment.Note, such as, such as keyboard 1832 and some subsystems of display 1822 may be used for and the function communicating relevant (such as, input carry out the text message transmitted by communication network), and device-resident functions (such as, calculator or task list).
The operating system software that processor 1838 uses usually is stored in the permanent memory of such as flash memory 1824, and as an alternative, this permanent memory can be read-only memory (ROM) or similar memory element (not shown).It will be understood by those skilled in the art that the volatile memory that operating system, specific device applications or its part can be loaded into provisionally such as RAM 1826.The signal of communication received also can be stored in RAM 1826.
As shown in the figure, flash memory 1824 can be separated into the zones of different for computer program 1858 and routine data storage 1850,1852,1854 and 1856.These different storage classes indicate each program can need to distribute for their data storage a part for flash memory 1824.Except its operation system function, processor 1838 can also realize the execution of the software application on UE.The predetermined set (comprising such as data and voice communications applications) controlling the application of basic operation is arranged on UE 1800 usually during manufacture.Other application can be installed subsequently or dynamically.
